Is gum arabic the same as gum tragacanth?
Gum Arabic is made from Acacia trees throughout Arabia and West Asia. Its gum is obtained through the sap from holes in the tree. Tragacanth is obtained from the dried sap of different species of the middle eastern legume.
What is the use of tragacanth in suspension?
Gum tragacanth is an effective suspending agent for many pharmaceutical products. It generally acts to suspend the active ingredient by increasing the viscosity of the external phase and thus prevents undissolved material from settling out.
What is the moisture content of tragacanth?
It consists of a water-swellable fraction called tragacanthic acid (or bassorin) (60–70%) and a water-soluble fraction called tragacanthin.
Is tragacanth gum soluble in water?
Tragacanth is one of the most acid-resistance gums and most efficient natural emulsifier for acidic oil-in-water emulsions [2]. Gum tragacanth consists two major fractions: a water-soluble (tragacanthic acid and small amount of an arabinogalactan) and an insoluble but water-swellable fraction named bassorin.

What are the components of tragacanth?
Tragacanth has 2 major constituents: tragacanthin (20% to 30%), a water-soluble fraction consisting of tragacanthic acid and arabinogalactan, and bassorin (60% to 70%), a water-insoluble fraction. Tragacanthic acid includes D-galacturonic acid, D-xylose, L-fructose, D-galactose, and other sugars.
What is tragacanth gum made of?
Gum tragacanth is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides obtained from sap that is drained from the root of the plant and dried. The gum seeps from the plant in twisted ribbons or flakes that can be powdered.
What is tragacanthin used for?
The major fractions are known as tragacanthin, highly water soluble as a mucilaginous colloid, and the chemically related bassorin, which is far less soluble but swells in water to form a gel. The gum is used in vegetable-tanned leatherworking as an edge slicking and burnishing compound, and is occasionally used as a stiffener in textiles.
